I have a 3 ring notebook, with a divider for each gun, so my 1st .22 caliber is 22A, the second is 22B, etc.
I mark each lot of brass for a speicific gun as 22A1, 22A2. The lot may be 20 rounds, 50 rounds, or 100 rounds, whatever container it is in.
I have a pre-printed sheet in a notebook for each lot of brass, and I check mark when procedures have been done: tumbled, inspected, resized, trimmed, annealed, etc. and end with a Ready-to-load Date, and a Date-loaded Date.
IF I keep it up, I can always know where a specific lot of brass stands. So when I wnat to load something, I can see which lot is ready, and pull it from the shelf.
I also keep my firing logs, info on the gun, pet loads, and keeper targets in the same place.
I can keep all my stuff in one large 2" notebook. Pretty handy right on the bench.
